Measure Big: How to Evaluate Impact at Scale


How do you design a system of social impact measurement when the impacts to be measured are incredibly diverse and those doing the measurement are spread across the country?  This was the task of Code for America, whose Brigade Network boasts over 80 chapters of civic tech volunteers across the United States.

In this session, you’ll learn from Brigade Senior Director Meredith Horowski and impact measurement specialist Mary Joyce how Code for America is using an iterative, participatory approach to develop its impact measurement system.

Learning Outcomes

  • Engage stakeholders to co-design your measurement system
  • Use stakeholder-generated impact data in system design
  • Build iteratively by testing, reflecting, and testing again

Target Audience

Leaders of organizations whose impact measurement requires large-scale coordination
